Cleaning text data
In the video, you saw how to build a custom function that performs a calculation and rounds the results. However, custom functions can be used for any task we expect to repeat! One common example is cleaning text data so that it conforms to specific requirements.
In this exercise, you'll create a function that takes string data and:
- Replaces spaces with underscores
- Converts to lowercase
- Returns the formatted string

clean_text, which converts characters inno_spacesto lowercase. - Finish the function by producing
clean_textas an output.
